TL;DR
This guide explains how to check resources usage in CloudLinux through cPanel and how to interpret common resource usage indicators. CloudLinux Resource Usage allows you to monitor how much CPU, memory, disk I/O, processes and other allocated hosting resources your account is using. In cPanel, open Metrics > Resource Usage to view current and historical usage and identify whether your account has reached a resource limit.
Overview
Monitoring hosting resource usage can help identify why a website is running slowly, returning errors or becoming temporarily unavailable. In a CloudLinux hosting environment, individual hosting accounts can be assigned resource limits that prevent one account from consuming excessive server resources and affecting other customers.
CloudLinux uses Lightweight Virtual Environment (LVE) technology to manage resources allocated to individual hosting accounts. Depending on the server configuration, these resources can include CPU, physical memory, input/output usage, entry processes and the number of processes available to an account.
A website may occasionally reach a resource limit during a short traffic spike or intensive task without indicating a persistent problem. Repeatedly reaching the same limit, however, may indicate that the website requires optimisation, that a plugin or application is consuming excessive resources, or that the hosting environment needs additional capacity.
CloudLinux resource monitoring provides information about the resources being consumed by your hosting account.
Common metrics can include:
- CPU Usage: The amount of processing capacity being consumed.
- Physical Memory: The RAM being used by processes associated with the hosting account.
- Input/Output (I/O): The rate at which the account reads or writes data.
- Entry Processes: The number of concurrent processes entering the account, commonly including web requests.
- Processes: The number of processes running within the account.
CloudLinux can restrict resources when an account reaches its assigned limits. Reviewing the usage history can help determine whether these limits are being reached regularly.

Steps to Check CloudLinux Resource Usage
1. Login to the Domains.co.za Customer Portal.
2. Open the Manage Services dropdown menu.
3. Choose Managed cPanel Hosting from the available options.
4. Click Manage next to the domain associated with your Managed cPanel Hosting package.
5. Click Login next to Control Panel to access cPanel.
6. Locate Metrics within cPanel.
7. Open Resource Usage or the available CloudLinux resource monitoring tool.
8. Review the current resource status for the hosting account.
9. Check whether cPanel reports that the account has reached any resource limits.
10. Open the resource usage details or history where available.
11. Review CPU usage for periods of consistently high processor activity.
12. Review physical memory usage to determine whether the account is approaching its memory limit.
13. Check I/O usage for unusually high levels of disk activity.
14. Review entry processes and process limits for periods where the account reached its allocated capacity.
15. Compare the times of resource spikes with website traffic, backups, scheduled tasks or other activity.
16. Investigate applications or processes that may be contributing to repeated resource limit events.
17. Monitor the account again after making optimisation changes to determine whether resource usage has improved.
What to Do If Resource Limits Are Reached
If the account repeatedly reaches its limits, investigate what was happening at the corresponding time.
For WordPress websites, common causes can include resource-intensive plugins, scheduled tasks, backup processes, security scans, high traffic, automated bots or inefficient database activity.
A single temporary spike may not require action. Consistently reaching resource limits should be investigated because it can affect website performance and availability.
Additional Information
- CloudLinux uses LVE technology to isolate and manage resources assigned to individual hosting accounts.
- CPU limits control the amount of processor capacity that an account can consume.
- Physical memory limits control the amount of RAM available to processes within the account.
- Entry process limits can affect how many simultaneous requests or processes can enter the hosting environment.
- I/O limits control the rate at which the hosting account can read and write data.
- A single resource spike doesn’t necessarily indicate that the hosting account requires an upgrade.
- Repeated resource limit events should be compared with website traffic and scheduled activities to identify possible causes.
- WordPress plugins, backup processes, security scans and scheduled tasks can temporarily increase resource consumption.
- Automated bots and unusually high website traffic can also contribute to resource limit events.
- Website optimisation, caching and database maintenance may reduce resource requirements in some situations.
- Resource limits shouldn’t be bypassed by terminating unfamiliar processes without first determining what those processes do.
- If a website consistently requires more resources than the hosting account provides, contact Domains.co.za Support to discuss the appropriate hosting options.
